The ColaSolar 12.8V 280Ah LiFePOâ‚„ lithium battery offers about 3.5-3.6 kWh of usable energy, with a built-in Battery Management System (BMS) for protection against overcharge, deep discharge, short circuits, and temperature extremes. Its nominal voltage is 12.8 V with operating voltage window roughly between 10.8-14.6 V. Because LiFePOâ‚„ chemistry is used, you get long cycle life (often thousands of cycles), high efficiency, and safer thermal behavior compared to lead-acid batteries. Etc
